Air Quality Sensors VOC and NOx (MOX) Gas Pollutant Sensor The SGP41-D-R4 is a compact digital gas sensor developed by Sensirion for indoor air quality monitoring applications. It is designed to detect volatile organic compounds (VOC) and nitrogen oxides (NOx) using Sensirion’s CMOSens® sensor technology. The device integrates sensing elements, analog front-end circuitry, calibration memory, and digital signal processing within a miniature surface-mount package, enabling accurate and reliable environmental sensing with minimal external components. The sensor communicates through a standard I²C digital interface and is optimized for low-power operation, making it suitable for battery-powered and portable electronic systems. The SGP41 is intended for use in air purifiers, HVAC systems, smart home devices, wearable electronics, environmental monitoring equipment, and other applications requiring real-time indoor air quality assessment. The device supports humidity-compensated measurements when paired with an external humidity and temperature sensor, improving long-term stability and measurement accuracy. Factory calibration eliminates the need for manual calibration during manufacturing.
